Common Galaxy S8 Plus issues we check at inspection

  • Screen burn-in on OLED display. Ghost images from status bar, navigation buttons, or keyboard visible on OLED panels after extended use. The S8 Plus's curved screen can exacerbate this.
  • Battery degradation below 80% health. Original battery showing <80% maximum capacity after 2+ years of use. This is typical for devices of this age.
  • Cracked or damaged screen glass. Physical damage to the screen glass, often from drops. May or may not affect touch functionality.
  • Faulty charging port. USB-C port becomes loose, corroded, or fails to charge reliably. Requires repair or replacement.
  • Water damage indicators tripped. Despite IP68 rating, internal indicators may show exposure to moisture, leading to corrosion and component failure.
  • Biometric sensor failure (fingerprint/iris scanner). Fingerprint sensor or iris scanner becomes unresponsive or inaccurate due to hardware or software issues.
